Abstract: Pyrocarbon is used as a coating material for fuel particles used in the High Temperature Reactor, and is deposited onto the fuel using a fluidized-bed technique. As a part of a basic research programme the microstructure of this pyrocarbon has been investigated by transmission electron microscopy. The deposition temperature and the concentration of the deposition gas in the fluidized bed were varied between 1100 and 2000 °C and 5 and 60 v/o C$_{3}$H$_{6}$ respectively. It is shown that three different types of structure are obtained in the pyrocarbon. The development of these microstructures is dependent on the deposition temperature and the concentration of the deposition gas. The properties of the microstructures, as deduced by transmission electron microscopy, are in agreement with the results of other material characterization techniques.
